FLAT FURUNCLE? PLASTER Filed May 22, 1951 Faiented May 1934 V FLATFURUNGLE PLASTER Emil Reinitz, Vienna, Austria Application May 22, 1931,Serial No. 539,347 In Austria, May 31, 1930 1 Claim. (Cl. 128-155) Thereare known chamber plasters in several modes of execution and structures;in most cases chambers are formed by felt inlaids, wound protectingcovers or similar means, said chambers serving for the reception of theoutflowing pus.

The present invention comprises a flat furuncle seal or plaster whichowing to its qualities may be regarded as belonging to the kind ofchamber plasters since according to the requirement a chamber isautomatically formed.

This purpose may be attained in the simplest manner. There is used anordinary adhesive or healing plaster, which is out out so as to form awindow or opening which is covered by a very thin, translucent andresilient, yielding rubber film being yet impermeable for the pus.

In the annexed drawing Figs. 1, 2 and 3, 4 show two modes of executionof the improved medical seal or plaster in a plan view and in a crosssectional view.

The frame of the seal as shown in Figs. 1 and 2 consists of two annularsticking or adhesive plasters 1, 2, the adhesive side of which is thelower one.

Before the rings 1 and 2 are united a circular rubber film 3 or the likeis placed on the adhesive side of the ring 1, said film having adiameter which corresponds approximately to the mean diameter of thering 1. After having united the rings or plasters 1 and 2 they form asingle ring like body, in which the edge of the film 3 is tightlyanchored. The seal furnished in this form being pressed with theadhesive side of the ring 2 to the skin closes completely the part to beprotected and prevents contaminations from getting access to the saidpart from outwards. The

sive plasters 1', 2', so that the edge of the rubber film 3 is heldbetween 1' and 4. The healing plaster 4 projects inward beyond the inneredge of the adhesive plaster 2'.

The frame of the closure or seal may have, of course, any suitable formand contour and may be if required cornered or oval. The improvedclosure or seal has compared with the chamber plasters and especiallywith the known arched wound protecting covers the advantage, that it isquite flat and adapts itself in case of requirement to the vaulted skinpart, so that it can form a chamber which may increase automatically ifnecessary.

What I claim is:

A plaster for boils, comprising a fiat plaster securing element adaptedto be applied directly to the body and to adhere thereto and having anopening to receive and expose a boil, and a thin elastic translucentrubber skin lying directly on and secured to said plaster securingelement and also lying directly on and revealing the boil and so that asthe size of the boil increases the said elastic, thin, translucentrubber skin bulges out because of its direct contact with the'boil.
